- I need to buy an air pump for a project
Hey all,
I've got a container that needs to maintain a certain amount of air pressure for the contents inside to develop correctly. However, it is an open container (like a big box with a hole in it), so without a pump constantly pushing air into it, it will rapidly drop pressure to equalize with the atmospheric pressure.
Now, I need to maintain a certain pressure, say N pascals, and I know the container is L x W x H centimeters and has a rectangular W2 x H2 cm hole in it. I need to figure out how many V liters per minute I need to pump inside given that I need to achieve N pascals and outside environment is in standard room temperature and pressure. I would be pumping normal "air" -- so whatever the normal air composition is.
Any ideas or direction as to the relevant formulas would be greatly appreciated. Thanks!
